EMBROiDE RlNGATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 262,003, dated August1, 1882.- Application filed January 30, 1882. (No modeL) To all whom itmay concern:

Be it known that I, FRANKLIN H. CHILTON, of New York, in the county ofNew York and State of New York, have invented a new and usefulImprovement in Embroidering Attachments, of which the following is aspecification, reference being had to the accompanying drawings.

The invention has relation to an improvement in embroidering attachmentsfor sewingmachines. M t

The particular nature of my invention will appear from the detaileddescription hereinafter presented, reference being had to theaccompanying drawings, in which- Figure 1 is a side view of anattachment embodying the elements of the invention. Fig. 2 is a top viewof same. Fig. 3 is a detached enlarged view of the lever and spiralshaft, and Fig. 4 is a detached view of the threadcarrier. Y V

A represents the foot of the attachment, which, in the present instance,consists simply of a plain fiat disk or piece having an aperture, a, forthe passage of the needle, and attached to the lower portion of asleeve, B, by which the embroiderer is attached to the presser-bar of asewing-machine in the customary manner.

Upon the side of the sleeve B is secured the bracket D, in the rearportion of .which is pivoted the rear end of the lever E, which passesforward and has pivotally secured in its'front end the loop (1. When theattachment is in use the loop d is arranged over the screw which securesthe needle in place. Thus the lever has an oscillating motioncorresponding with the movement of the needle-bar.

Upon the foot A is secured the stationary thread-detainer 6, being asmall projection or bar arranged to extend partially in front and to oneside of the aperture 00.

At about the center of the foot A is set the lower end of the verticalspiral or twisted shaft M, the upper end of which is held in ahorizontal extensiomf, of the bracket D. The spiral shaft M is arrangedto have a free rotary movement when actuated, and carries upon its lowerportion, close to the upper surface of the foot A, the thread-carrier N,which consists of a shank and a circular hook-shaped portion,

a, the point of the hook-shaped portion n being notched, as indicated at.00, forming two of the lever E the point of the thread-carrier willcome opposite to the eye h, in proper relation to catch theembroidering-thread, which extends from the eye It into the aperture a,and to drawit at the succeeding upward movement of the lever E aroundthe thread-detainer, and to a point in rear of the vertical line of thesewing-needle, as indicated in Fig. 2, whereby a loop is formed, whichis drawn to the proper size and sewed down at the next following strokeof the needle-bar and lever E.

The principal feature of my invention-i-s'in operating the spiral shaftby a lever, by which arrangement 1 accomplish various objects which havebeen thought to be impossible in attachments where the thread-carrier isoperated by a spiral shaft.

Among other advantages I gain in driving the spiral shaft by a lever isthe adaptability of theattachment to any of the machines now in use. Itis well known that the spiral shaft driven by a traveler or fixedconnection can be applied to but few machines, owing to the fact of theneedle and presser bars being too close together to permit of the spiralshaft being inserted between them and the interference of the head ofthe needle-screw, threadcutters, 860. By the use of the lever for thepurpose described thev spiral shaft may be thrown out from theneedle-bar and operated without interference and with ease and rapidity.

A furtherand very important fact to be mentioned is that by employingthe lever having a loop, d, the attachment may be applied to machinesvarying in the stroke of the needlebar without altering the length ofthe spiral tension m, in combination with the shaft M and shaft, thedifference in stroke being regnlated with a thread-carrier andthread-detainer, subby the 10st motion in the loop. stantially as setforth.

What I claim as my invention, and desire In testimony that I claimthe'foregoing i-m- 15 to secure by Letters Patent, is provement inembroidering attachments, as I 1.
